Get Base Rotation and Base Offset in Meters

This Blueprint returns the current rotation and position of the headset with respect to the most recent base rotation and position, expressed in meters.

The base offset is the translational difference between the current position of the headset and the most recent base position set using Set Base Rotation and Base Offset in Meters. It is a vector that translates the headset position into the (0,0,0) point in meters. The axes of the vector are the same as for Unreal: X is forward, Y is right, and Z is up. When the user recenters the headset from the original center of the tracking space, the base offset is the delta from the center of the tracking space to the new center of the game space (or “world space”).

Similarly, the base rotation offset (returned as Out Rotation) is the rotational difference between the current rotation of the headset and the most recent base rotation set using Set Base Rotation and Base Offset in Meters. It is an FRotator construct with Pitch, Roll, and Yaw properties.

This Blueprint expresses its values in meters. In each Unreal Engine world, you can define the scale factor of the world, which scales everything in the world consistently. By default, the scale factor is 100, which means the system expresses values in centimeters instead of meters. You can use any scale factor you wish. Regardless of the world scale factor, this node always returns the base offset in meters.

This node wraps UOculusXRFunctionLibrary::GetBaseRotationAndBaseOffsetInMeters in the OculusLibrary Blueprint category. It is a pure Blueprint node with no execution pins.
